Solution is to use the maven-failsafe-plugin which will in the integration test phase. You need to this to your pom file:

<project>
  [...]
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-failsafe-plugin</artifactId>
        <version>2.19.1</version>
        <executions>
          <execution>
            <goals>
              <goal>integration-test</goal>
              <goal>verify</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
  [...]
</project>

You should following the conventions and follow the naming conventions of integration tests:

<includes>
 <include>**/IT*.java</include>
 <include>**/*IT.java</include>
 <include>**/*ITCase.java</include>
</includes>

Afterwards you can run those integration tests via:

mvn clean verify

If you like to run only unit tests:

mvn clean test
